FIG. 105. Rate of oxygen consumption of 122 Euphousio pacifica at 10°C; the dry
consumption at temperatures between 0" and 15°C were measured by
McWhinnie and Marciniak within 30 min of catching E . superba. The
consumption of oxygen rose slightly between animals kept a t 0" and
5°C but animals kept at 10" and 15°C showed no further increase in
